You can put this solution on YOUR website! Hi, my name is Aaron I am in 10th grade and im in honors trig/pre-calc. I dont feel like doing my hw, so I will do my best to help you.
we will use the factor therom to prove this.
Set each answer choice to zero, to find the zero of it. ex 4x-3=0 so x=3/4
plug x=3/4 into 8x^2 + 22x - 6 if it equals zero then you have your answer, if not repeat the same steps for letter B.
Hope I helped. If you need a better explanation please feel free to contact me. A note of thanks is always appreciated. Good luck

2[4x(x + 3) - 1(x + 3)]
2(4x - 1)(x + 3)
Looking at the 1st two factors, 2(4x - 1), and distributing them, we see that one of the factors is: (CHOICE C)
